Granite quarrying presents tougher challenges than marble mining: higher rock hardness, strong abrasiveness, dense mineral grain structure and frequent natural joints inside the granite massif. Improper mining easily causes block cracking, fast diamond bead wear and low recovery rate. This on-site case shows multiple Stonewin quarry wire saw machines working at the same bench of a large granite quarry, realizing batch cutting of granite blocks and greatly lifting the overall mining productivity.

This granite quarry mainly produces commercial granite blocks for domestic slab factories and overseas export. In the past, the quarry relied heavily on circular saw cutters and blasting-assisted mining. The large circular saw has heavy power consumption and limited cutting depth; blasting creates hidden cracks inside granite, downgrading high-grade blocks and raising scrap rate. As market demand for standard granite blocks grew, the customer decided to expand mining capacity by introducing several Stonewin quarry diamond wire saws and arrange them for simultaneous cutting on the same quarry platform.

Each Stonewin wire saw runs independently on its guide rail. Operators set separate cutting parameters for each machine according to the local granite hardness, rock bedding and crack distribution. Multiple cutting kerfs are formed at the same time on the granite face. Compared with single sequential cutting, this parallel layout shortens the whole quarrying cycle and allows the quarry to harvest more qualified granite blocks per shift.

Stonewin quarry wire saw is optimized for hard granite conditions. The heavy-duty traction structure delivers stable pulling force to avoid wire jitter; the intelligent constant-tension control system automatically adjusts wire tension to reduce wire breakage caused by uneven rock hardness. The machine body is built to withstand muddy, water-rich quarry working conditions, with good waterproofing and dust resistance for long continuous operation. It can cooperate with big circular saws to complete combined mining: the circular saw makes horizontal cuts, and wire saws finish vertical splitting of granite blocks.

After long-term running on site, the customer has obtained obvious benefits. Internal micro-cracks from blasting are eliminated, so more high-quality granite blocks can be supplied to slab processing plants. The service life of diamond wire is improved, and the comprehensive consumption cost is under better control. Flexible arrangement of multiple wire saws also makes production scheduling easier. When one unit needs maintenance, other machines can keep working to avoid full-line shutdown.

This granite quarry project proves that Stonewin diamond wire saw is a mature and reliable solution for hard rock quarrying. For granite mine owners who want to replace blasting, increase block output and improve ore yield, deploying multiple wire saw machines for simultaneous cutting is a highly efficient mining scheme.
